Abstract: A device is provided for sterile coupling of a percutaneous surgical instrument to a rotary drive tool (5). The device has a flexible envelope (1) confining the drive tool (5), a connector piece (3) coupling to the percutaneous surgical instrument via one end, and to the drive tool (5) via its other end, by passing through the envelope via an opening (12) A tubular ring (2) is positioned on the inner surface of the envelope (1) in the area of the opening (12) and is configured to rigidly connect the envelope (1) to the body of the drive tool (5). The connector piece (3) passes through the ring and turns freely inside the ring when driven by the rotary drive tool (5). The connector piece (3), the ring, and the envelope interact in order to form a leaktight barrier between the inside and the outside of the envelope (1) in the area of the opening (12).

Abstract: The invention relates to an anchoring device for registering lesions or microcalcification in a biological tissue, comprising: a guide wire comprising at least one graduated portion for determining the anchoring depth of the anchoring device, at least two anchoring members for anchoring in a biological tissue connected to the guide wire, and a connecting ring connecting the guide wire to the anchoring members. The invention relates also to an anchoring system comprising such an anchoring device, a mandrel and a hollow positioning needle.

Abstract: The invention relates to an osteosynthesis device intended for holding, distraction or compression of fragments of a fractured bone. The device comprises a threaded pin (1) having a threaded head (2) at its distal end, and a ring (4) adapted to slide on the threaded pin (1). The pin (1) and the ring (4) are made of materials allowing them to be cut. The ring (4) has at its distal end a threaded head (5) whose diameter is at least equal to the diameter of the threaded head (2) of the pin (1). The threaded pin (1) and the threaded ring (4) are hollow so as to allow them to be crimped during the cutting.
